HO GP7 Locomotive with DCC and Sound, RDG #629 (ATHG82721)

HO GP7 Locomotive in RDG green with yellow trim, featuring DCC and sound, brings authentic Reading Company diesel power to HO-scale layouts. Designed for long-hood-forward operation, this model reproduces era-specific RDG details such as the L-shaped grabs on the short hood, cab rain gutters, and a Leslie S3L horn—delivering a faithful representation of 1950s freight power.

Beyond its appearance, the GP7 offers dependable performance and careful detailing. It rides on a heavy die-cast frame with Blomberg-B trucks, includes see-through cab windows with a full interior, LED lighting, and fine-scale Celcon handrails. The model is DCC-ready with Quick Plug 21-pin NEM connector and features RP25 wheels for smooth tracking, while sound-equipped variants use a DCC decoder with SoundTraxx Tsunami2 and dual speakers for realistic audio. It runs on both DC and DCC, supports NMRA-compatible functions, and is designed for an 18-inch minimum radius with body-mounted scale knuckle couplers compatible with Kadee.
